Need tests for GenerateAzureDevOpsBuildManifest

This file was created for the Post-Build Signing project, so it should be tested in it's entirety in relation to that project.

Related PRs:

• Create modified msi package drop #5442
• Add build manifest #5210

Code that needs unit testing:

@jonfortescue https://github.com/dotnet/core-eng/issues/9658 should be covered too. Folding that into this.

@jonfortescue What is the status of this? Trying to figure out where I can help out on testing.

@chcosta ETA for this is EOD next wednesday.

I think this can be tested by completely removing it. We don't use the manifest generated by this: #6528

We do need tests for the manifest generation in PushToAzureDevOpsArtifacts though https://github.com/dotnet/arcade/pull/6528/files#diff-2c204b59d01e73c04c5834f945685c3f74bbe862e33de4b58cd2ebc47f200cd1R150

@mmitche yeah, I had mentioned completely removing it as a possibility and I think that is probably the best path forward. I wasn't sure if I was missing something, but if we can delete code that we're just not using that would be A++

Removed code. Will backport to release/5.0 after it makes a round through the normal master, #6529
